Question 4:

If the angles are the same (two 45° and one 90°) the vertical side is equal to side C. the Pythagorean theorem states that A²+B²=C².

if Side C is equivalent to 4, both sides of the right angle are 4 (Because they are equivalent to each other.) so 4²+4²= 4 x
`√(2)` (5.8) so D=5.8, C=4

D is roughly 1.45 C
